Tyco 557.202.007.Y XLM800 Loop Expansion Module

Tyco 557.202.007.Y XLM800 Loop Expansion Module

The XLM800 Loop Expansion Module fits "piggyback" style onto the FIM or an existing XLM 800 used to:

• Expand the capability of the MX4000C.I.E. two loop system to four six or eight loops 
• Replace the FIM loops in case of a failure on either a two or four loop system

The XLM800 Loop Expansion Module controls the communications between the detectors (and other ancillaries) connected on the 2-wire loop circuits and the controller. In addition, the addressable interface contains line isolation circuits which protect the loop driver circuit from short-circuit conditions.
